Sweet potato (Ipomoea batatas (L.) Lam) is an economically important and a food security root crop produced in Ethiopia. However, the production and productivity of the crop is low at national as well as regional level which is constrained mainly by low soil fertility. Lack of recommendation on appropriate rates of blended fertilizers and cattle manure is one of the problems limiting the production of sweet potato. A study was conducted to determine the combined effect of blended NPSB fertilizer and cattle manure rates on growth, yield and yield components of sweet potato at Bako Agricultural Research Center from December to April 2019/2020 using furrow irrigation. The treatment consisted four levels of blended NPSB fertilizer, (0, 50, 100 and 150 kg ha-1) and three levels of cattle manure (0, 5 and 10 t ha-1). The experiment was laid out in a Randomized Complete Block Design (RCBD) in a factorial arrangement and replicated three times. Data were collected on phenological, parameters growth of sweet potato. These data were subjected ANOVA using SAS (version 9.3) software. The results of analysis of variance showed that main effect of blended NPSB fertilizer and cattle manure rate were significantly (P < 0.01) affected and their interaction (p>0.05) affected. The number of branches per plants (NBPP), vein length (VL), total number of tuberes per plant (TNTPP) shoot fresh weight (SHFW), shoot dry weight (SHDW), The highest vine length (149.6cm), was recorded at 10 t ha-1cattle manure +150 kg NPSB ha-1, while the lowest vine length (108.10 cm), was recorded at control. In conclusion the result indicated that the growth, of sweet potato at study area can be improved by combined application of 150kg ha-1 NPSB blended fertilizers and 10 tone ha-1 cattle manure rates. As recommendation, further study needs to be conducted by considering higher combined application of blended NPSB fertilizer and cattle manure rates to find optimum growth of sweet potato that enables to obtain better result and to generate more reliable information.
